Our latest work in progress is by far one of the coolest extensions ever created for the Magento eCommerce platform. It is going to change the way people use Magento.
In short, the extension allows the store owner to upload a CSV price sheet to enable table-based and matrix pricing for Magento. Custom options/attributes are automatically generated based on CSV headers/column titles. Price offsets are field based (column -> row).
It will also be possible to use the CSV file for “range-based” pricing. For example, user inputs two values on the front-end of your store, x and y, and the price will be determined by their intersection point or range of intersection on the price sheet.
If you are interested in participating in the beta testing for this extension, please post a comment on this post. We will email you at the address you provide when ready. Our goal is to see all the different price sheet variations out there so we can come up with an extremely diverse extension with amazing options.
